Scattered storms rolled through Central Indiana lifting from south to north and arriving in time for the evening commute Friday.  Locally, heavy downpours accompanied the storms.  Rainfall amounts of 1.70″ were reported in Alexandria with 1.36″ in Knightstown.  Officially, the city received .31″ of rainfall.  The soggy spring rolls on – with 59 percent of the days this Spring (since March 1) with a trace or more of precipitation.

Storm Clouds approach the city Friday afternoon

The rain chance continues this weekend but do not cancel any outdoor plans.  Yes, be prepared to move indoors especially during the afternoon hours but Friday may be a snap shot of the type of day we are expecting Saturday.  Afternoon heating will activate showers and thunderstorms by late morning in to early Saturday afternoon.  Area coverage on the rainfall could reach 50 percent on Saturday but that coverage drops for Sunday.  The latest thinking is that Sunday will be the better of the two days this weekend.  The rainfall chance is dropping Sunday and Monday only to rise again early next week.  Coverage Saturday will reach 50 percent and drop to 30 percent Sunday.  While we cannot rule out rainfall and thunderstorms either day, there will be a better chance of rain Saturday.  By no means cancel ou-door plans but be prepared to move indoors for 45 minutes or an hour as the rain passes through.


Rainfall coverage next 6 days. Chance of rain lowers for Sunday


Temperatures have approached the 80° for several days after reaching 85° Wednesday.  The warmest air of the season looks to move in Monday along with the highest levels of humidity so far this season.  Upper 80’s Monday could produce a heat index into the low 90’s before storm thunderstorms return.


A chance of storms through the weekend will once again be on the climb as severe storms break out in the central plains.  The slow moving storms system will bring showers and thunderstorms through the state Tuesday through Thursday.  Severe storms are a possibility Tuesday but not a guarantee at this point.  We will monitor.

Severe Outlook Day3

Severe Threat spreads east by early next week


It’s still a ways out but indications are that a cold front will settle south through the state Friday (Carb Day) with a shower or storm possible then.  High pressure dropping south from Michigan will lower humidity and bring a beautiful stretch of weather Saturday through Monday.  It’s looking 15° to 20° cooler for race day compared to last year.  Be sure to check back – the key is when and where will that cold front stall.
